We will now be separating the main board from the watch.

You will be gently prying up on the main board in the area that the spudger is located in the second picture.

Be extremely careful while prying up on the main board. Be careful not to bend the board and make sure all cables that are loose are out of the way of possibly getting ripped.

Do not fully remove the main board, as the button cable is soldered to the main board. Carefully place the main board in the orientation shown.
